Clouds are one of the least understood aspects of climatechange. They can block the sun, but light can also bounce off one cloud into another cloud’s shadow and increase the solar energy hitting earth. Fair-weather clouds are big puffy white objects that bounce a lot of light around. —Evgueni Kassianov.
It is a strategy rooted in cross-cutting research and engineering to enable industry stakeholders, communities, government agencies, and early adopters to meet their climate goals. In NREL’s bioenergy program, for example, we have chemists studying the fundamental chemistry of converting biomass and waste materials into fuel.
Other evidence also suggests that BC deposition in the Arctic is partly responsible for arctic climatechange, the authors note. In contrast, published BC emission factors for light-duty gasoline vehicles (LDGV), derived from near roadway/tunnel sites or chassis-dynamometer studies, indicate LDGV to be relatively minor sources of BC.

Robert Dorner and his colleagues are looking at converting CO 2 and hydrogen (both won from sea-water) over catalysts, using the CO 2 as a building block to form synthetic fuel. This catalyst converts the feed gas predominantly to methane under all conditions (ca. Robert Dorner.
Up to 77% of the world’s energy supply could be met by six key renewables by mid-century under the most optimistic scenario if backed by the right enabling public policies, according to a new report by more than 120 researchers working with the Intergovernmental Panel on ClimateChange (IPCC).
We are the first to use both light and heat to synthesize liquid hydrocarbons in a single stage reactor from carbon dioxide and water. The eventual replacement of oil with fuels generated from sustainable and carbon-neutral sources is necessary if we are to avoid harmful climatechange due to the buildup of greenhouse gases in the atmosphere.
This reactor converts a portion of the volatile gases into a mixture of light olefins, predominantly ethylene and propylene. This process, like gasification in the gasification/F-T processes, effectively normalizes the volatile gas feed by converting it into a gas stream that is relatively independent of the feed composition.
The new findings, published in the journal Nature ClimateChange , have implications for long-term emissions and climate modeling, as well as climate policy. Current climate and energy system models typically don’t explore the impacts of oil reservoir depletion in any detail. c, Light oils. a, Heavy oils.
